How about gifting your dad a book on Galileo Galilei's life and accomplishments? "Galileo: A Life" by James Reston Jr. is a great option. You could also consider a framed print of one of Galileo's famous astronomical drawings or a telescope so that he can stargaze just like his favorite scientist did. Additionally, a Galileo Galilei bust or a keepsake that represents his life's work such as a miniature model of the telescope he built would make a great decorative piece for your dad's office space or home library.
Or you can get him a star map with an important date you share.
